Description
Theoretical uncertainties in the simulation of $t\bar{t}b\bar{b}$ production represent one of the main obstacles that still hamper the observation of Higgs-boson production in association with top-quark pairs in the $H \to b\bar{b}$. We present a next-to-leading order (NLO) simulation of $t\bar{t}b\bar{b}$ production with massive b-quarks matched to the Pythia within the POWHEG method with the hope of reconciling tension between previous calculations based on the MC@NLO method.
